CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 516,680, dated March20, 1 894.

Application filed February 27, 1893. Serial No. 463,928. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH GRAUVOGL, a citizen of the United States,residing at Plain, in the county of Sauk and State of Wisconsin, haveinvented a certain new and use fullmprovement in Railroad-Oar Couplers,of which the following is a specification.

My invention relates to improvements in railroad car couplers, and theobjects of my improvement are first, to promote and provide for thecoupling and uncoupling of cars satisfactorily, expeditiously and safelywithout'the danger to loss of life and limb encountered by going betweenthe ends of cars and over or between the tracks inorder to couple anduncouple cars, and to reduce to a minimum the loss of life, limb andproperty occasioned by the'expeditious uncoupling of cars while a trainis in motion; second, to provide a suitable machine or mechanismforsatisfactorily, expeditiously and safely coupling anduncoupling carsto accomplish the ends and purposes above mentioned.

The accompanying drawing is an isometric projection showing the bottomand end of a railroad car with thedevice in position.

A, is the buffer of a car having the proper shape for the operation ofthis device.

B. is a coupling link having two extensions C. and fastened to thebufier by pin D.; and

connected with extensions 0 are two rods E.,v

which in turn are connected with the crank F. by means of its two armsG. F. is securely fastened to .the bottom of the car by hearings toallow the necessary rotary motion.

The operation of "the device or mechanism is performed as follows: Bysuitable means a rotary motion is imparted to the crank which raises andlowers the link and allows it to be dropped into or raised out of anotch in the buffer; and the device or mechanism can be operated andcars coupled together and securely locked, or unlocked, by suitabledevice for the transmission of power from any portion of the car ortrain or any position adjacent thereto, and by its operation thecoupling and uncoupling of cars can be accomplished with the greatestpossible dispatch and with the minimum of danger to loss of life andlimb and property; and further the device may be easily and simplyattached to existing cars at small expense, its parts being few innumber, simple and substantial, and unlikely to get out of repair.

I claim for this invention the following:

In a car coupler the combination of a buffer having the curved hook onupper surface A. a coupling link B. with two slightly curved rigidextensions 0. fastened to the buffer by pin D. as an axis, two rods E.connected by pin with extremity of extensions 0. rods E. connected withcrank F. by means of its rigid arms G. and with crank F. parallel withand near the end'of car, securely fastened to the- I bottom of the carby bearings to allow the necessary rotary motion as indicated in thedrawing, and substantially as specified.

Dated at Madison, Wisconsin, February 16, 1893.
